User patterns
The TRF-598 TV (SAT) generator can store up to 5 user patterns. User patterns are always
designed for 525 lines or 625 lines mode. You can use it in any picture format, but if the current
screen format differs from designed, geometric distortion or clipping can occur.
User patterns contain one or two fields. In the first case you can select "I1", "NI" and "NL"
scanning mode, in the second case the "I2" mode, too. Generator memory can contain up to 5
fields, so you can store 5 patterns with one field, or 1 pattern with two fields and 3 patterns with
one field or 2 patterns with two fields and 1 pattern with one field.
This patterns are completely user definable. You can create it using bitmap picture editors or
download required patterns from internet. From factory the generator is fitted with the most
popular set of patterns.
If you want to create special patterns (monoscopes, anti-PAL and so on), you should use "TRF
Manager" software. The last version is very powerful and you are able to create your own
patterns "in a minute or two". Moreover you can create teletext pages, store current TRF-598
configuration to disk, save preselections, retrieve it and many more.
TRF-598 monoscope example and multiburst example (format 4:3, 625 lines, 50 Hz)
Teletext
From factory the TRF-598 contain set of most popular teletext pages. If you want to create
your own teletext pages or teletext rasters, use "TRF Manager" software.
Teletext pages may be edited at different levels: starting single byte editing up to visual design.
Visual mode is the simplest way how to create new teletext pages. Advanced designers can use
packet editors, too.
The TRF-598 is able to generate any teletext pages, you design. See ETS 300-706 teletext
specification for detail information about teletext.
Teletext pages count is limited only by available memory. The TRF Manager show you how
many bytes are free, when you design new pages.
Teletext is transmitted inside three lines during vertical blanking interval, by default. You can
change lines and fields as you need, when using TRF Manager.

TRF Manager
The "TRF Manager" CD contain software packs that help you:
- create your own test patterns or modify completed,
- change standard patterns,
- create your own teletext pages and rasters,
- edit preselections,
- configure TRF-598 from PC,
- and many more!
Moreover the CD contain set of completed user patterns, standard patterns, teletext pages,
preselections and another data files.
You can find here various utilities, documentation and teletext specification ETS 300-706.
Installation
Insert CD into computer, open folder "TRF Manager" and run installation wizard named
"SetupENG.exe". Select installation type, destination folder and run installation.
Program "Pattern Viewer" show pattern files (PNF extension) content and is automatically
associated with this file type. You can run it by double clicking the pattern file.
Other programs are associated with appropriated file types, too. But you can find them in
"Start/ Programs/ TRF Manager" and run it directly:
- TRF Manager ...main program (TRF-598 control, project administration and so on),
- Pattern Creator ...creates your own patterns.
TRF Manager
Data for TRF-598 TV pattern generator are prepared in form a project. The project you can
open or save to disk and upload to generator. Project is divided into several separated parts
(patterns, teletext, ...). Many of them you can individual open or save to disk, upload to
generator and, in case of preselections, download from generator. You can select requested
project part in the tree located near left side of program window.
When you work on new
project, you should first select
device type. Device can be
changed later, but not all
properties are supported by
all types.
But it is very helpful if you
have more generators and
want setup them to the same
state.
This window enables you
add comment to project, too.

Bars, areas
If you select in project tree bars pattern, at the right side appear editor. At the top is pattern
number and type and at second line pattern name. If selected device support name changes,
you can type your own name here.
Note, the name length is limited. Delete previous text before you type new (use Del key for
example).
Center part of editor show
pattern preview. Click on bar
and set colour coordinates as
you need.
Click button "Previous" to
restore pattern to previous
state or press "Standard"
button to restore pattern to
default state. Above buttons
you can see appropriate
pattern preview.
Changes are stored to
project by button "Apply all".
If you select in project tree
area pattern, you can edit it in
a similar way.
Bars pattern editor (areas pattern editor is similar)
User patterns
In project tree select one of five user patterns. On the right appear user pattern property editor
and pattern preview (if auto preview function is enabled, see "Setup").
At the top is pattern number and name. Set cursor at the first or second line and type your own
name. Note, the name length is limited. Delete previous text before you type new (use Del key
for example).
If pattern preview is not
visible, press button "Refresh
preview". If you need larger
preview, press button "Large".
Pattern parameters are at
right. All user patterns are
stored to project, but only
"Available patterns" are
uploaded to generator. Note,
the total field count must be
less or equal to 5.
Background colour is used
only after vertical frequency
change or if you import
smaller bitmap image.
Changes are stored to
project by button "Apply all".
To create new user pattern,
use "Pattern Creator".

Teletext
If you select in the project tree teletext raster or teletext page, editor appear at right. The term
"teletext raster" mean a subset of term "teletext page". While teletext pages can contain any
(different) packets, teletext rasters contain only two packets: 0 and 1. The rest of page up to
packet nr. 23 is filled with packet 1 content. So teletext pages can contain any number of
packets (limited only by available memory), while teletext rasters have fixed packet count (24)
and take far less memory,
than full teletext pages.
Teletext editor allows you to
name selected page. The
name including page number
is then visible in project tree.
Page number is given by
packet nr. 0 content (see
teletext specification). You
should set it first, because
program keep "magazine"
number. Teletext packets may
be edited by three different
ways.
The most common is
"Packets data editor". Use
this editor to change single
bytes (indexed $04..$2d) in
any packet.
Moreover you can add new
Teletext editor (packets data editor selected)
packets, remove, clear or
move packets to any location in page. This editor allows you to set the same magazine number
for all packets together.
If you select some packet, then you can edit it in "Packet editor". Packet editor allows you to
enable or disable automatic computing of parity bits. This option is needed for all standard
packets, otherwise you have to add it manually. Parity bits are added when data are uploaded to
generator, so data inside packets editor are unchanged.
Packet editor enables you to set magazine number, packet number and designation code.
Packet data are displayed in mode according to these values.
Packet nr. 0 allows you to set many teletext parameters (see ETS 300-706). Above all you can
set page number units and tens, enable special functions, select character set and fill visible
part.
Visible part is divided into two sections -lower (bytes indexed 14 to 37) and upper (bytes 38 to
45). Upper eight bytes are usually used for time display, let us say for characters visible at any
page. Default teletext pages use this section for raster (page) index formatted "_R01/P--" for
rasters and "_R--/P01" for teletext pages. Top right corner of TV receiver then show what is at
the moment transmitted and how fast.
Next packets may be edited by bytes (in hexadecimal, binary or character notation), or by
triplets (in hexadecimal or binary notation). The most significant digit is at left, the least
significant digit is at right. Characters may be written as hexadecimal codes preceded with "#"
character, too ("#1e" for example).
Packets nr. 0 to 23 and packets nr. 24, 25 may be edited using "visual editor". If you edit
teletext raster, then only packets nr. 0 and 1 may be modified. Packets nr. 2 to 23 are the same
as packet nr. 1. Standard teletext pages may be edited freely.
In center of visual editor is design grid. If a bar on left side is visible (cursor is blinking), you
can insert characters using keyboard. After key is pressed, cursor moves at right. Use common
keys to set cursor at requested position.
TRF-598 (brief)
Page 8
Characters, you can insert, are divided into three groups. First group contain special control
characters called "spacing attributes" (code $00 to $1f, see ETS 300-706). Second group
contain alphanumeric characters and the last group contain graphic characters called "mosaic"
(code $20 to $7f). You can insert characters using keyboard, pop-up menu or click them in table
on the right. Use spacing attributes to change alphanumeric characters to mosaic and vice
versa. In design time click icon above table to show alphanumeric or mosaic characters.
Invoke pop-up menu using right mouse button above design grid. If your keyboard support
Windows keys, use appropriate key. The menu allows you insert character by code, switch
character table to alphanumeric or mosaic, move visual editor into sizeable separate window or
repaint design grid.
On the top of editor you can select alphanumeric and mosaic character set. This set is used
only in design time. Use packet nr. 0 (or packets nr. 28, 29, etc.) to force teletext decoders
switch to requested character set.
In design time you can use any character sets (it is helpful if you use packet nr. 26). If you click
"Repaint" button (or when you type into new packet), the design grid is repainted using selected
alphanumeric and mosaic set.
Press "Apply all" to save changes into project.
In project tree is always visible "New page" and "New raster". Select this item to create new
page or teletext raster. Change the page name and when you press "Apply all" button, the page
will be added into project. If you want to determine rasters or pages transmit order, use project
tree pop-up menu. Invoke this menu using right mouse button over appropriate page (raster) in
project tree.
The pop-up menu allows you to remove selected page, too.

come up to device key where the preselection is stored and bank symbol give press count to
recall requested preselection.
In project tree select preselection you want to edit. At the right appear editor that enables you
to change preselection parameters. At the top is preselection number, bank and name. Change
the name, if selected device
support it.
Note, the name length is
fixed. Delete previous text
before you type new (use key
Del for example).

Melody
The TRF-598 support beep and melody signals. When some event occur, then linked beep or
song is played. For example, if you press key then you can hear song that depend on key
function. There are many events, by default the most of them are linked to short beep or to "no
sound" and only a few play longer songs (after startup, for example). The TRF Manager helps
you to create your own signalling scheme. You can open songs in MIDI type 0 or PianoMan 4
formats and import it entire or
only get a part.
List box "Songs" show the
imported songs, you can link
to events. Events and linked
songs are listed below.
Use spacebar to play song
or "Enter" to link it to selected
event.

Environment parameters
TRF Manager allows you to customize program environment. Select "Setup" bookmark and
set folders, colours and another parameters. Changes may be valid only before you close the
program ("Apply all" button pressed only) or you can store applied changes as default using
"Save" button.
Be careful when you select communication port number. The TRF-598 TV generator have to
be connected only to valid
parallel (LPT) port of your
computer. Use only original
cable and connect the TV
generator into PC only after
program call you. If you
disappoint this rules, you can
damage computer and
generator.
If you are not able to find
port number under Windows,
contact your computer dealer.
Press "Try connection" to
check communication.

Pattern Creator
Use "Pattern Creator" to design your own television test patterns and signals. The program
menu contain following items: "File", "View", "Insert" and "Help".
File
Init new design by selecting "New" or open existing PCF file using "Open". To close file use
"Close" menu item. Changes you can store using "Save" or "Save as" items.
You can save designed pattern either in component format (PCF extension) or in pattern
format (PNF extension). Component files may be opened and modified using Pattern Creator,
while pattern files are created only for TRF Manager and for transfer to TRF-598. Components
files may be converted to pattern files, but pattern files cannot be converted back to components.
Use "Exit" to close the program.
View
User pattern is created from components. All components you add are listed in Pattern Creator
window and you can change its order or properties. You are able to hide some components, too.
Current pattern preview is visible in separate window after you select "Pattern" item. Note, it is
preview only and some special signals (anti-PAL, etc.) are simplified.
If "Auto refresh" is checked, then all changes will appear in preview window immediately.
Otherwise you have to select "Refresh" item.
When "As is" checked, then pattern will be displayed without distortion given your computer
monitor resolution. But in this mode the picture format is always incorrect.
"Sizeable" item allows you to change size and picture format as you need (not available in "As
is" mode). Use standard window elements to make this changes. Note, you change only
preview window, not real pattern format. Pattern format is specified when you select "File/ New".
Insert
To insert a pattern component, use this menu item. Select required component from
"Graticule", "Shapes", "Anti-PAL" signals, bars, sin waves and many other. After you select
component, you can set its properties.
Help
If you need help, pick this menu item or press "F1" key.
